ILR on Tier-2 Route (Absence Letters)

Hi All,
I have been following up this site for preparation of my ILR application on Tier2 General.
I would need your advise on couple of queries, if you could point me into right direction.

1. I had switched from Tier-2 ICT to Tier-2 General visa on 15-Mar-2013. I had some medical issue, so i had been to India for medical treatment on 20th April 2013 and returned back on 5th june 2013, the same treatment happened in UK before but not succeeded. I don't have medical certificate to provide but i have got an original Discharge summary letter, will that be ok ? any other evidence required to be shared ?

2. On Feb -2014, i had been to india for holidays for a week , i was paid for the duration but my employer won't provide me letter as i had been switched to different sponsor. what other proofs can be shared.

3. After switching to different sponsor I had been to india for wedding for a week and got the letter at that time, will that letter be still be valid or i need to ask for a new letter as i am currently working for another sponsor?


4. My wife will be eligible for PBS (Tier-2 dependent extension)- is this process online in UK, she had applied last time from India.

5. My Son was born in UK on Dec-2016 and hasn't hold any passport at the moment as i have been planing to apply for Naturalisation. should i apply for my Wife first then son or other way around ? any idea how much will it take for him to get the process completed.


I would appreciate your support if you could advise on above queries.

Hi All,
Please advise on any of the queries as it would help me with planning and preparation.


Thanks in advance.
